Abstract
A reference signal transmission method is provided to reduce power consumption. The method may be applied to time-frequency tracking. The method includes a network device sends configuration information of a reference signal RS to a terminal device, where the configuration information is used to indicate at least one periodic target sending time period of the RS; and the network device sends the RS in a first target sending time period based on a first periodicity, where the first target sending time period belongs to the at least one periodic target sending time period. In this case, the RS is sent only in a part of the target sending time period, that is, the RS is not an always-on signal, and wake-up duration of UE is short. This helps UE reduce power consumption.
